    Blood Type
AI Thread Summary
The discussion centers around the validity of Dr. D'Adamo's claims regarding blood type diets. Critics argue that there is little scientific backing for his theories, labeling him as a pseudo-scientific figure who relies on anecdotes rather than controlled studies. The assertion that genetic factors influencing digestion align with blood types is met with skepticism, as it is believed that human populations have not been isolated long enough for significant genetic divergence based on diet. While some participants acknowledge that certain genes, like lactase and amylase, show variations among populations, they emphasize that these are not novel genes but rather variations in gene copies. The consensus leans towards the idea that D'Adamo's claims lack substantial scientific evidence, and any potential benefits of his diet recommendations are likely minimal. Future advancements in genome sequencing may enable more personalized dietary approaches, but current claims about blood type diets remain largely unsubstantiated.

Is there anything to this?

"http://www.dadamo.com/" ."

Any truth to Dr. D'Adamo's claim, other than getting people to sign up for his program?

While i can respect that train of thought, i have a hard time believeing that all the genitic factors that could relate to how we digest and use food would follow a pattern that matches up with blood type. Never mind the fact that we havnt been separated as a population long enough for truly novel genes to have developed based on diet. Small beneifits at the best imho.

Now, how diet affects your health is very complicated and still being worked out.

For an interesting case study review how LCAT deficiency doesn't increase atherogenicity while MTP deficiency does.

I think the short answer is: No, there probably is very little science in the claim.
 
D'Adamo is considered a pseudo-scientific quack. He uses anecdotes and not controlled studies to support the validity of his ideas. His claims of when the different blood types emerged, are also not backed by any facts.

It is generally believed that type A is the earliest, due to that alleles coding for blood type A are the most ancient version of the ABO blood group, shared by primates/humans. He takes great liberty's in deciding which blood type came first.

If he had even one controlled study, on any aspect of his grand ideas. Perhaps the medical world would think of him as something, other then a quack.

Agreed.

We have been. Lactase is a classic example. Amylase is another. An average caucasian American has almost double the number of copies of the amylase gene AMY1A compared to an average pre-agriculture African. There are large variations within ethnic groups too.

In ten years or maybe even sooner, full genome sequencing will become affordable to a regular person, everyone will be able to tailor their diets to their specific genomes.

Yes but those genes are just copies and not new "novel" genes. A person with more copies will do a slightly better job with a food but nothing really different.
